I.15. Changes from 2.2.1 to 2.2.2

The configure option "--with-lib" has been replaced by "--with-dev".
This enable the additional build and distribution of the static
version of libupsclient, along with the pkg-config helper and manual
pages. The default configure option is to distribute only the shared
version of libupsclient. This can be overriden by using the
"--disable-shared" configure option (distribute static only binaries).

The UPS poweroff handling of the usbhid-ups driver has been reworked.
Though regression is not expected, users of this driver are
encouraged to test this feature by calling "upsmon -c fsd" and
report any issue on the NUT mailing lists.
